LIMITING
PULSING
If an overload or a short circuit is detected (U
out
drops below the voltage
limit U
srt
) then the current is limited by the DBL charger:
If the voltage on the output drops below U
srt
then the current is
limited to 0,5A.
If the voltage on the output drops below U
srt
then the current is limited
to a fixed value of 0,5A for about 60 seconds. After this time interval the
current limit rises in order to test if the overload / short circuit is present
longer.
Altogether three pulses are given out from the DBL – should the overload /
short circuit be present any longer then no more trials are taken and
current is limited to max. 0,5A until a reset of the device.

CABLE:
Carry out the cable compensation:
In order to start the measurement of the cables resistance the cables
attached to the DBL during supply/charging process have to be short-
circuited on the free end without any load.
Choose the menu item START and confirm by pressing the ENTER-key.
If the cable compensation has been carried out successful then the
measured resistance value is shown in the display (e.g. R: 0,029 Ω)
Cable resistance R: 0.000 Ω
Shows the measured / preset cable resistance value. If the resistance
value is selected directly in the menu, then the user is able to chose
between the value determined at the cable compensation and R = 0.000Ω
(no cable compensation.)
